1. A method of making an implantable stimulator, the method comprising:
- forming a polymer-polymer interface between two portions of the implantable stimulator, each portion of the implantable stimulator comprising a polymeric component;
disposing a light absorbing metal layer on the interface; and
irradiating the light absorbing metal layer with a laser to heat the metal layer to weld the interface forming a direct polymer-to-polymer bond between the two portions of the implantable stimulator, wherein the direct polymer-to-polymer bond comprises a region in which the polymeric components of the two portions of the implantable stimulator are in direct contact with each other and directly bonded without the light absorbing metal layer between the polymeric components.

Abstract
An implantable stimulator that includes a housing, a first plastic component, and a second plastic component, where the first and second plastic components form a polymer-polymer interface. A light absorbing metal layer is disposed over at least a portion of the interface and an electronic subassembly is disposed within the housing. The first and second plastic components can be welded together by irradiating the light absorbing metal layer which converts the light to heat.
